Table 3 List of the four types of RMS present within different S. Typhimurium phage types as confirmed by REBASE [44]

From: Whole genome sequencing provides possible explanations for the difference in phage susceptibility among two Salmonella Typhimurium phage types (DT8 and DT30) associated with a single foodborne outbreak
